ROCKING-CHAIR.

` SPECIFICATION forming part of Letters Patent N o. 643,192, dated February 13, 1900.

Application ined september 25,1899. sentira. 731,583. (Numan.)

To al?, wtont it may concern:

Be it known that I, ALBERT LoMMATZscH, a citizen of the United States, residing in Jersey City, Hudson county, and State of New Jersey, have invented certain new and useful Improvements in Rocking-Chairs, of which the following is a specification sufficient to enable others skilled in the art to which the invention appertains to make and use the same.

My improvements are designed more particularly for rockingchairs for child rens use, although the essential features of the invention are applicable to rocking-chairs of all sizes.

The invention is designed to afford a collapsible or knockdown rocking-chair which may be quickly and conveniently adj usted for use or folded away in compact form for storage or transportation, the connection of the parts under all conditions being maintained.

The invention consists in the special construction and arrangement of parts substantially as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a top view of my improved rocking-chair, partly in section; Fig. 2, a view of theunder side thereof; Fig. 3, a top view showing the device collapsed. Fig. 4E is a central longitudinal section, and Fig. 5 asectioual detail of one of the folding rungs.

The side members or rocker-frames R, provided with the rockers r, are of any desired or usual construction. Both the seat S and the back-rest B are hinged to one or the other of said side frames R, rests or shoulders s and b being provided upon the opposed side frames to sustain the seat and back when extended. Fastening devices are provided for holding the seat and back extended between the rocker-frames R. As shown in the drawings, these locking devices are shown as consisting of hooks and eyes 7L e, arranged and engaging with each other in the well-known manner, although it is obvious that other mechanical expedients may be substituted with like result. The cross-braces are also made so as to fold in between theside frames R. Thus the foot-rest F (when used) may be hinged to one or bothof the rocker-frames R. This combined cross-brace and foot-rest F is shown in the drawings as consisting of two leaves ff, respectively attached pivotally to the opposed rocker-frames R R, and connected centrally by a hinge f on the under side. A bolt f2, attached to one leaf, engages with a socket upon the other leaf for the purpose of locking the cross-brace or foot-rest F in its extended position. This foot-rest F is used mainly upon small rocking-chairs designed for the use of children, but may be omitted without departing from the spirit and intent of my invention. Other crossbraces or rungs are provided for other parts of the chair-frame, as the rear rung T and the front hand-rail H. The rear rung T is in the nature of a toggle, consisting of two parts t t, hinged together centrally, the outer ends being pivotally connected to the rocker-frames R R and the brace being held in its extended position by means of a sleeve T', fitting over adjoining ends of the members t t, as will be readily understood by reference to Fig 5 of the drawings. By making the rear rung T and the front brace or foot-rest l each in two parts hinged together centrally and connected at their outer ends pivotally to the rockerframes I insurea positive connection between the rocker-frames R R and the other parts of the device under all conditions, so that even when collapsed there is no danger of loss or displacement of any part of the device. The cross-brace or hand-rail H is preferably made in one piece hinged to one of the rocker-frames R and engaging with the opposing rocker-frame when extended. Thus in the drawings its free end is adapted to t into a mortise r'in the opposed rocker-frame R, as shown in Fig. 1, and it may be locked positively in this position by a catch or bolt r2, engaging with a socket or recess h', formed in the said cross-brace H.

It is obvious that the seat S or back-rest B may be hinged to either one or the other of the rocker-frames or that one may be hinged to one side frame while the other is hinged to the opposite side frame with like result. It

is also obvious that the seat S may be employed without the back-rest B, if desired, the essential and distinguishing feature in this construction of chair being the combination, with the side rocker-frames R R and with a folding seat hinged to one side rockerframe, of front and rear toggle-joint cross- IOC braces by which the side frames R R are coupled together under all conditons What I claim as my invention, and desire to secure by Letters Patent, is

1. In a collapsible rocking-chair, the combination of two rocker-frames, a plu rality of toggle-jointed cross-braces coupling said rockerframes togetherpermanently, means for holding the said toggle-braces extended, a seat hinged to one rocker-frame and engaging with a supporting-shoulder upon the other rockerframe,and said seat-supportin g shoulder, 'substantially as herein described.

2. In a collapsible rockin g-chair, the combination of two rocker-fram es, a plurality of toggle-jointed cross-braces coupling said rockerframes together permanently, means for holding said toggle-braces extended, a seat hinged to one rocker-frame and engaging with a su pporting-shoulder upon the other rocker-frame, said seat-supporting shoulder, and a handrail hinged to one of the rocker-frames and engaging positively with the other rockerframe, substantially as herein set forth.

3. In a collapsible rocking-chair, the combination of two rocker-frames, a plurality of toggle-jointed cross-braces coupling said rockerframes together permanently, means for holding the said toggle-braces extended, a seat hinged to one rocker-frame and engaging with a supporting-shoulder upon the other rockerframe, said seat-supporting shoulder, a backrest hinged to one rocker-frame and engaging with a supporting-shoulder upon the other rocker-frame, and said back-rest-supporting shoulder, substantially as herein described.

4. In a collapsible rocking-chai r, the combination of two rocker-frames, a plurality of toggle-jointed cross-braces coupling said rockerframes together permanently, means for holding the said toggle-braces extended, a seat hinged to one rocker-frame and engaging with a supporting-shoulder upon the other rockerframe, said seat-supporting shoulder, a fold ing foot-rest consisting of two leaves hinged respectively to the two rocker-frames and to each other, and means for holding said folding foot-rest in an extended position, substantially as herein set forth.

5. In acollapsible rocking-chair, the combination of two rocker-frames, a plurality ot' folding cross braces coupling said :rockerframes together permanently, means for holding the said cross-braces extended, a seat hinged to one rocker-frame and engaging with a supportingshoulderupon the othei rockerframe, said seat-supporting shoulder, the rear toggle-brace T, and the sleeve i, for holding said rear brace extended, substantially as herein described.

6. In a collapsible rocking-chair, the combination of the two rocker-frames R, R, the hinged seat S, the supporting-shoulder s, the hinged back-rest B, the supporting-shoulder b, the foldingfoot-rest F, the hand-rail H, and the toggle-brace T, the whole arranged and operating substantially in the manner and for the purpose described.
